Copper oxide composites were successfully synthesized by a catalyst-free method, plasma arc technology. The as-synthesized composites were characterized by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and x-ray photoelectron spectroscopy. The analysis revealed a mixture of crystalline copper oxide (CuO), cuprous oxide (CuO) and copper (Cu) phases of the copper oxide composites constitute of irregularly spheroidal particlesµ with nanoparticles aggregate on the surface.

There was a significant difference between the mean plasma and whole blood concentrations of both cobalt (Co) and chromium (Cr) (p < 0.0001 for both Co and Cr).

The aim of this study was to investigate whether our integrated health system, composed of academic hospitals, a practice plan, and a managed care payer, could reliably implement an evidence-based program for gastric bypass surgery. A secondary aim was to evaluate the impact of the program on clinical outcomes.

Frontloading was effective for patients with heart failure, decreasing rehospitalization by more than half (39.4-16%), with fewer visits (15.

There have been earlier studies evaluating the efficacy of early initiation of enteral feedings that had encouraging results. However, delayed initiation of feeding following PEG placement continues to be practiced widely.

Our objectives were (1) to characterize physical function themes based on combinations of tasks (deriving factors or components) and (2) to quantify the correlation between derived factors and body mass index (BMI).
Research Methods And Procedures: Nutrition risk screens from enrollees in a Medicare-managed risk program served as the sampling frame.
